no, for that you can use the ClutterCairo texture actor provided by the clutter-cairo integration library. since Cairo does not have an OpenGL backend[1], the ClutterCairo texture will give you a context from an image surface and will then proceed to dump the contents of the drawing onto a GL texture. it's quite easy to write a composite actor with a ClutterCairo as an internal child to draw a background, for instance; I've done it in my Twitter client 'Tweet'[2] to have backgrounds with antialiased rounded corners. ciao, Emmanuele. +++ [1] though Pippin has been working on an experimental OpenVG backend.
